TRANSMISSION APPATUS.

Application filed July 311,

To all whom it may concern:

Be it known that ll, EooUARo BELIN, a citi i zen of the Republic of France, residing at 31 Boulevard lLuchet, Paris, France, have invented certainv new and useful Transmission Apparatus, of which the following is a specification. 1

In the specification of Patent No. 915154 is described a system of transmitting to a distance all kinds of graphic documents, this system being based on the employment at thetransmittlng stationof an original presenting a surface in relief and an apparatus which permits of utilizing this relief for the variation (continuous, graduated, or irregular) of the line current received in an optical system. I

The apparatus which forms the object of the present application is designed for the purpose of obtaining with minimum size.

and weight a complete transmitting station capable of being connected with the line at the end of whichthe receiver is arranged.

Reference willnow be had to the accompanying drawings forming a part of this specification wherein: a

Figure 3 is an elevation of the end of the apparatus opposite to that shown in Figure 1.

Figure 7 is a sectional view through the apparatus shown in Figureti.

Figure 8 is a detail view of the operative or driving onnection between the movablecarriage an the drive shaft.

Figure 9 is a diagrammatic View of the electrical connections for the apparatus.

The motor groupl-ln abox or container 1 is disposed a powerful spring-contained in a barrel 2, capable of'being wound from the exterior by the application of a-key (not shown) to the stem 3, andthis actuates, through a suitable train of multiplying gearing. a speed regulator t, thus providing for a practically constant speed which can easily W13. fierial Ito. 782,3t7.

be determined from the exterior of the casing in the usual-manner. Tn addition, to this the spring drives a pinion 5 through the intermediate gearing, including the Worm 3 and shaft3. On the box 1 may be fixed a suitable resistance 7 when a rheostat is employed or a combined rheostat and'microphone of the type hereinafter mentioned.

The v trmzmm'liter .The transmitter comprises a structure embodying the two end standards or supports 8 and 9 fixed upon a plate and interconnected by meansof spacmg rods 10 and 11. A worm shaft 12 is arranged between the two standards-aand actuated by the pinion 5 through the intermediate gear 13. This worm, by "its rotation, produces the regular longitudinal displacement of a surface exploring arrangement embodying certain points hereinafter referred to. The gear 13 also drives the upper shaft or spindle 14 which carries the cylinder 15 containing the stereotyped block or other record to be transmitted. The worm 12 and the shaft 14; should rotate in such a manner that the movement of the exploring point in contact therewith describes on the cylinder a helix of determined pitch (one-third of a millimeter, for instance), accordin to the extent of the detail of the cut or re ief which is to be transmitted. The

In order to insure perfect parallelism between the two axes 12 and 1.4:, the latter is carried at its two ends by the eccentric points 23, 23' (Fig. 5). The point 23,115 a relatively fixed point once the proper adjustment or positioning of the same in itssup porting standard has been set. But the point 23 is capable of such adjustment as to bring thetcylinder into proper alignment with the shaft 12 that proper contact of the transcribing points will be maintained throughout the movement of said points over the surface. The end of the spindle of the cylinder may be raised and lowered by properly adjusting the point 23 which is accomplished by its rotation, the point being free to rotate when the clamp 20 is released standard support by means of a pin 19 proiecting therefrom into a slot 19. Against this a jam nut 18 acts to lock thenut 19 on the threaded end 16, preventing rotati-ve movement of the point 23 in its standard support, while permitting of longitudinal movement as desired in application of a cylinder between the two points. -A nut 17 1s 5 mounted upon the threaded part 16 so that when it is desired to move the point 23 inwardly this is backed off to accomplish this purpose, after which it is screwed up against the face of the standard and fixes the point L0 23' fast in its mounting. A jam nut 17' is mounted on the end of the threaded portion 16 to coact with the nut 17 just referred to, to prevent accidental displacement. Once the points 23 and 23 have been thus adjusted, they are allowed to remain permanently fixed. In other words, this 1(l]11Stment will be maintained although it is possible to remove the cylinder by merely releasing the handle 20 to permit of the point 20 23 being shifted longitudinally to accomplish the displacement.

The clockwork mechanism shown in Figure 2 may be replaced by a small electric I motor, either alternating or direct. In F 1g- 25 ure 6 is shown this modified arrangement,

the figure being a front elevation. The motor 31, through multiplying gearing, actuates a vertical shaft 31 which drives the spindle 14 of the cylinder 15. In the draw- 3 ing a reducing system for the worm drive 12, which is employed to drive the carriage upon whichthe exploring points are mounted, is shown. The pinions, 32, 32' produce a lower speed than may be obtained through 35 the pinions 33, 33 and in this manner the exploring point acting upon the surface of the cylinder 15 will make a greater or less number of turns of the helix per unit length, and the relief surface will accordingly be more or less finally reproduced, for example, with six lines or witlrthree lines to the millimeter. A clutch handle 34 permits the change from one speed to the other. The omission of the spring barrel and all of the parts shown in the preferred form will naturally produce a lightening of the apparatus. This is an advantage in a portable device of this character.

The carriage R which is mounted to travel longitudinally of the cylinder, and which is adjustable transversely thereof. embodies three exploration systems. Reference has been made 'hereinbefore of the use of a combined rheostat and microphone, and this instrument is designated by Rm in Figure 6, the form of this instrument being of a known character andspecifically depicted in my prior Patent No. 1,143.487, granted June 15, 1915. This instrument is mounted upon the support or fork 24 forming a part of the base 26' and arranged at one side of the cylinder. The base 26' is slidable transversely of.the cylinder upon the carriage 26 by means of the screw 27, through the. instrumentality of which the point 37 of the instrument may be moved into and out of contact with the relief surface. At the opposite side of the cylinder is mounted an interrupter having the point 35 arranged to coact with the relief surface when it is desired to employ this instrument instead of the instrument Rm, so that the adjustment by the screw 27 will bring either the point 35 of the interrupter into contact with the surface or the point 37 into such contact, or an intermediate adjustment may be obtained where neither of these points will be in contact, under which last mentioned condition the carriage may be freely moved longitudinally of the cylinder. The carriage 26 is mounted upon the two side rails 28 arranged parallel with the screw 12, and a thread-engaging member or knife 29, shown most clearly in Figure 8, engages with the screw so as to produce the longitudinal displacement of the carriage in the exploring of the surfaces. Lifting the knife member the carriage will be free to slide longitudinally as above referred to.

The rapid rotation of the electric motor may be utilized for sending into the line yery strong variations of current. If direct current is employed, a branch is nissed through a rotary interrupter 30 which produces a large number of pulsations in the circuit. This circuit passes to the primary of a transformer, of which the secondary is arranged in the line, as shown most clearly in Figure 9. The microphone is connected in shunt with the source of current which feeds the motor.

It will be understood that there is preferably employed a friction drive between, the motor and the pinion on the shaft 38, in order to avoid shocks and longitudinal vibrations 0f the motor.

If an alternating current motor is being employed, any welhknown approved means may be utilized for interrupting the line current.

The arrangement in lligure 9 discloses the connection for supplying. the line with direct current.

In a portableapparatus for transmission of documents by relief, the combination of a cylinder carrying the relief surface. means for rotating the cylinder, an exploration system arranged at each side of the cylinder and shiftable longitudinally thereof, and a common means for shifting either of said ex )loration systems into contact with the relief surface.
